A spokesperson said the statements were "inaccurate"

Qualcomm suddenly has an about-face regarding Apple's 64-bit A7 processor, which a company executive called a "marketing gimmick" just last week.

Anand Chandrasekher -- senior vice president and chief marketing officer at Qualcomm -- said last week that Apple's 64-bit processor in the new iPhone 5S doesn't offer a big enough reason for consumers to upgrade because 64-bit chips are needed for memory addressability beyond 4GB, and the iPhone 5S has only 1GB of DRAM. Hence, he concluded that 64-bit processors are not relevant in today's smartphones and tablets. 

"I know there's a lot of noise because Apple did [64-bit] on their A7," said Chandrasekher. "I think they are doing a marketing gimmick. There's zero benefit a consumer gets from that."

However, Qualcomm is backtracking on those comments and now says that 64-bit processors are a necessary part of the future of mobile computing. 

“The comments made by Anand Chandrasekher, Qualcomm CMO, about 64-bit computing were inaccurate,” said a Qualcomm spokesperson. “The mobile hardware and software ecosystem is already moving in the direction of 64-bit; and, the evolution to 64-bit brings desktop class capabilities and user experiences to mobile, as well as enabling mobile processors and software to run new classes of computing devices.”

Qualcomm works closely with Apple and supplies modems for iPhones and iPads. Also, both companies design chips based on ARM architecture. 

More specifically, the A7 chip is based on the ARMv8 instruction set, which is said to boost performance through quicker mathematical and security tasks. It also eliminates the inefficiencies in older ARM instructions, but some wonder how much credit the 64-bit processor can take for the heightened performance. 

Apple released its iPhone 5S last month, which runs $199/$299/$399 for 16GB/32GB/64GB respectively. 

Qualcomm provides its Snapdragon chips for Android and Windows Phone smartphones and tablets. It even plans to continue investing in chips made for Windows RT, which is a mobile version of Windows 8 that runs on ARM-based chips and has been criticized for failing to produce a full Windows 8 experience (it can't run legacy apps).  

Qualcomm said it plans to offer a 64-bit processor in the future to keep up with chip designs and even cut manufacturing costs, but there's no set release date.

5s is a phone you can buy now and which will never get more RAM.


The advantages and significance of the transition to 64 bit chip architecture in the iPhone 5s, and the huge leap in speed it achieved, has nothing to do with the amount of RAM that can be addressed. That's a red herring that hypnotises the technically illiterate and is just another example of old style PC thinking being applied inappropriately to new mobile technologies.

Try to visit web sites with a bit more technical background.

This is a good place to start.

There are only a few places where ARMv8 based processors get a significant increase in speed. Most of these places are due to the new instructions added to the ARMv8 spec rather than bitness.

One place that can 64-bit can improve is data movement operations where data is placed in a register while being transitioned from source to destination. This is a direct result of 64-bit wide general purpose data, instruction pointer, stack pointer and index pointer registers being able to move double the data in the same amount of time in comparison to a 32-bit architecture.

Note also that the majority of this improvement will only be seen under AArch64 applications. If you are running 32-bit AARch32 applications on this platform (the vast majority of applications offered in the Apple store), you will see NO significant performance improvements at all.

"the huge leap in speed it achieved" also don't have anything to do with 64bit. Those tricks don't work on me.

There are places where 64-bitness of the ARMv8 data and pointer registers of ARMv8 that can provide up to a double speed increase, and there also are new instructions in AArch64 that make a big difference in specific operations such as encoding/decoding (though these really are not tied to the bit-ness of the processor).

But that is where it stops. AND you won't get those benefits without applications that are compiled to use AArch64. The vast majority of applications in both Apple and Google Play stores are and will be 32-bit (AArch32) applications for the foreseeable future. AArch32 is relatively unchanged to prevent anomalies from creeping into running those existing 32-bit applications.
